MACHINE FOR BENDING BRIDLE-IRONS.

SPECIFICATION formingpart of Letters Patent No. 656,936, dated August 28, 1900.

Application filed January 25, 1900. Serial No. 2,713. (No model.)

T0 aZZ whom it may concern.-

Be it known that I, JEREMIAH BUoKLEY, a citizen of the United'States, residing at New York, borough of Manhattan, and State of New York, have invented certain new and useful Improvements in Machines for Bending Bridle-Irons, of which the following is a specification.

This invention relates to machines for making bridle or stirrup irons such as are used for supporting beams, joist-s, or timbers in the construction of buildings.

The object of the invention is to provide a machine of the described class which is effective and which can be used to turn out the articles quickly and in various sizes.

The invention consists of certain features of construction and combinations of parts to be hereinafter described and then claimed.

In the accompanying drawings, Figure 1 is a side elevation of a machine for bending bridleirons embodying my improvements. Fig. 2'

for bending up the hooks of the bridle-iron on line 9 9, Fig. 0. Fig. 10 is a side elevation of the twisting-tool, showing how it is applied to the strip to be twisted. Figs. 11, 12, and 13 are perspective views showing the step of forming the loop, the twists, and the hooks; and Fig. 14: is a perspective view showing how the iron is used.

Similar letters of reference indicate corresponding parts throughout'the drawings.

Referring to the drawings, A indicates the bed of the machine, on which the parts are mounted, and B 13 indicate movable blocks which by means of dovetail tongueandgrooved connection at b are guided upon the said bed or base piece,O being a screw-spindle having handles 0 O and provided with right and left threads meshing in corresponding threads in the said blocks, as clearly shown in Figs. 4 and 5. One end of the bed or base A is provided with a longitudinal ex- 5, and is adj ustable by means of a forwardlyextending slide-rod E, shown partly in dotted lines and partly in full lines in Fig. 4, and having an adjustable handle E which is provided with a screw e, entering the end of said rod, so that when the handle is rotated it is moved to or from the said rod, The position of the handle E regulates the distance of the anvil E from the rear of the machine, while a pivoted bifurcated stop a, controlled by handle a at the front end of the machine,

takes over the said screwe and prevents the handle, and hence said anvil, from moving farther to the rear than the position set. The anvil E is removable from the slide E being attached thereto by a countersunk screw 6 so that anvils of different sizes can be placed in position. (See dotted lines in Fig. 5.) The anvil E is provided with a separable section F, which is shown as swinging on a hinge or pivotf and which is provided with a tenon or projection f, that enters a socket c in the anvil E, and is thereby adapted to assist in fixing the anvil in set position and to compose with the same a former over which the metallic strap for the bridle-iron is to be bent. Said anvil-section F is pivoted atfto a suitable hinge-plate G, which receives a squared transverse rod g, that is guided loosely at both ends in flanges H of two laterally and longitudinally movable slide-plates H H, on which a top plate G is mounted. The slideplates H H are provided with tongues h on their side flanges h, which tongues fit in grooves 71 in the sides of the blocks B B, so that said slide-plates H H can move longitudinally of the machine, in doing which they carry with them the top plate G and its sup ported parts. The top plate has a tongueand-grooved connection at 9 with the slide VAA,

plates, so that the latter can move transversely of the machine with the slide-blocks, said top plate remaining in position. To secure the top plate to said slide-plates, the latter are provided with upwardly-projecting screw-threaded studs or pins g, which pass through slots g in said top plate, nuts 9 bein g screwed onto said studs, which when loose permit the blocks 13 B and the slide-plates H H to be spread apart or come together, and then, when the desired adjustment is produced, the nuts are turned down against the top plate, so as to prevent relative movement of the parts. The before-referred-to guiderail D is, as shown in dotted lines in Fig. 4, supported in central fixed position by extending the same rearwardly from the under side of the top plate G.

The side flanges h of the slide-plates H H are provided with teeth 70, which are engaged by weighted and hand-operated pawls K, pivoted to the sides of the blocks B B, so as to hold the top plate G and slide-plates in adjusted forward or backward position. As shown in detailin Fig. 7, the adjacent ends of the upwardly-extending flanges 1-1 of the slide-plates 1-1 H are provided with dovetailed recesses W, in which dovetailed bearers t' are guided, said bearers supporting, by means of screws 2', the hinge-plate G and also supporting a pair of pivoted jaws I I, one at each side of the anvil and arranged to move in a plane at right angles to the plane of movement of the upper anvil-section F. The said pivoted jaws operate at each side of the anvil E and are moved by means of an upwardly-extending hand-lever J, which is pivoted to the bed A at A and which-is also pivoted by means of links J to a slide J guided in ways j of the top plate G and connected in turn by means of links J to the jaws I 1, said links J passing through suitable guideholes in the flanges H The links J are provided with ratchet-teeth, (see Fig. 3,) which are engaged by hand-operated pawls J pivoted to the top plate G, so that said pawls will hold the jaws I I in parallel closed position at each side of the anvil. A handle F is pivoted to the upper anvil-section F and is provided with a slotted lug F which is adapted to engage a pin F on aforesaid slide J to hold the said anvil-section in raised position, while when said locking parts are disengaged the anvil-section F may be moved down upon the anvil E.

The described anvil and the folding jaws are for the purpose of forming the loop or socket of the bridle-iron, as hereinafter described. The central rail D and the upper surfaces of the blocks B B are recessed at Z l to receive the notched jaw L of the twisting-tool shown in Fig. 10, which imparts the twist to the bridle-iron and lays the shanks of the same down flat upon the blocks B B.

M M are retainers which are arranged on opposite sides of the anvil in pairs and are pivoted at m to the side blocks B B, they being in normal position within the recesses m in the said blocks, so that they will be flush with the upper surfaces of the said blocks and not interfere with the folding operation in forming the loop of the bridle-iron. Said pivoted retainers are operated by means of oscillatory shafts N, which are pivoted in suitable bearings n at the sides of the slide blocks B B and carry-arms n, which are connected by pivoted links 01 to the said retainers, said arms being secured on the shaft by means of set-screws n The shafts N are each provided with a hand-wheel N.

The extension or wing A has been referred to. It is mounted adjustably or so as to slide in the bed A, being operated by means of a screw-spindle A provided with a hand-wheel A and its screw-thread meshing in a corresponding screw-thread of said extension, so that the extension is moved inwardly or outwardly by the corresponding movement of said spindle. Projecting from the extension A is a guide-post O, on which is guided a sleeve 0, pivotally connected with the rear end of a lever 0 (see dotted lines, Fig. 4,) that is pivoted to an upward extension A at the front end of the base A, so that the said lever moves in the space between the blocks B B. The lever 0 when depressed raises the sleeve 0 and parts mounted thereon, said lever being locked in depressed position by means of a hook O pivoted to the front end of the bed. Secured by collar 19 to the said sleeve 0 or in any suitable way is a crossbar P, on the arms of which slides P are guided and are set in adjusted position by means of thumb-screws 19. These slides P carry a pair of bending-jaws Q, which are pivoted thereto at q and are provided with handles q. Lips R of L shape are mounted adjustably on the operative faces of said jaws by means of set-screws r, said lips having a tongue-and-grooved connection at r with said jaws, so that the same are adjustable toward and away from the pivots q. The said bending-jaws O are held in raised inoperative position (shown in Figs. 1 and 5) by means of a pivoted button r which is arranged on the sleeve 0.

S indicates a forked holder, one arranged on each oscillatory shaft N and held thereon by a set-screw S, which when swung up into vertical position receives the cross-bar P and slides P when they are moved down into the position shown in Figs. 3 and 4:. Springactuated catches N engage at their forked ends over the squared shafts N and hold the forked holders S and retainers M M in upright position.

The rear ends of the slide-blocks B B are recessed at b below and in the plane of movement of the bending-jaws Q, so that when the sleeve 0 is lowered the said bending-jaws may enter the said recesses and form the hooks of the bridle-irons, the recessed ends of the blocks thus serving as anvils.

Guide-post 0, before referred to, while it is carried by the adjustable extension A, is mounted directly on a hinged portion 25' of said extension, so that the post and the parts carried thereby may be swung out away from the rear ends of the blocks B B. This is done by means of a pusher T, which is guided in the bed A between the blocks B B and is connected at its rear end by a link t with said hinged portion i, said pusher also serving to bring the parts back to upright position.

Longitudinal openings V pass through the blocks B B, and in the same are placed a pair of bars V, which at their front ends receive the ends of handles W, swiveled therein, (see Fig. 4,) said handles each having a notch W for engaging a projecting lug W on each block, whereby said bars are locked in position. The rear ends of the bars V are provided with a longitudinal anvil extension or toes V thinner than the said bars and located to one side thereof.

The operation of the machine will now be described.

The operator first takes a strip of iron Y and places it transversely of the machine against the stop-gage Z,with its mid-length in between the anvil E and the opposing dovetailed bearers c. He now releases the handle F from pin F" and lowers the anvil-section F down onto the anvil E, whereupon the lever J is pushed in, so as to close the jaws I 1 upon the metallic strip Y, and bends and folds the same against the sides of the parts E F, the cross-bars P being mean while raised into the position shown in Figs. 1 and 6, so that the ends of the strip Y may move under it, as shown by dotted lines, Fig. 1, whereby the loop 50 of the bridle-iron X, Fig. 13, is formed. The retainers M M and the holders S are now raised upright into the position shown by dotted lines in Fig. 5 by turning the oscillatory shaft N in proper direction and securing it in position by means of the catches N Then the operator places the notched jaw L of the twisting-tool L successively over the upper edges of the strip Y at a point opposite the transverse top recessesl Z, so that when a turn from horizontal position through an angle of ninety degrees is given to the tool the head of the same will enter said recesses, the twists at 00 will be given the shanks 00 of the bridle-iron, and the ends of the strip beyond the twists will be turned in a plane at right angles to the plane of the portions lying at each side of the anvil, so as to be laid down flat upon top of the blocks 13 B. The twisted shanks are prevented from spreading and are held in line with the end recesses b of the blocks B B by means of the upright side retainers M M. The operator now releases the lever 0 from the hook O and the cross-bar P and slide P, carrying the parallel jaws Q, are lowered by their own weight down upon the blocks B B, the outer ends of the crossbar and slides beholders S, whereby the said parts are firmly held against twisting or other movement relatively to the machine. The button r for retaining the jaws Q upright is now turned so as to release the same, the handles q of the jaws being grasped and the jaws pressed forcibly down into position shown in Fig. 4, thus bending the projecting ends of the strip, so as to form the hooks m of the bridle-iron. The ends of the strip are bent by said jaws Q around and upon the recessed ends of blocks 13 B and the thin anvil extensions V of the bars V, the blocks forming the corners or bends 00 of the hooks and the anvil extensions the corners or bends 00 To remove the so bent-up bridleiron, the parts described are returned to normal. position and the pusher T is pushed in, so as to act on and swing the hinged portion tand the parts carried thereby away from the rear end of the machine, as shown in dotted lines in Fig. 4, thus releasing the jaws Q from the hooks of the bridle-iron. A clearing rod or slide U, guided on top plate G, is now pushed against the loop of the bridle-iron so as to push the anvil E rearwardly, and thereby release and clear the hooks of the bridle-iron from the recessed ends of the blocks B B, whereupon the bridle-iron is then readily raised from the anvil E and removed from the machine. The pusher T is then pulled so as to return the actuated parts to upright position, the machine being now ready to form another bridle-iron.

The different portions of the machine are adjustable in evident manner for turning out bridle-irons of various sizes.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. The combination, in a machine for bending bridle-irons, of the bed, transverselymovable blocks, a supporting-rail between the blocks, an adjustable anvil mounted on said rail and projecting always above the said blocks, means for bending the head or loop of the bridle iron around said anvil, and means for bending the hooks of the bridleiron over the ends of said blocks, substantially as set forth.
